Search results love one horsepower number for the 560SL. Reality splits by market. US cars carry emissions equipment and tune that cut peak horsepower versus some European figures — and you should buy a US car on US manners, not a Euro magazine quote.

US vs Euro — the honest split
European 500/560 family cars were often rated higher in period literature. US 560SLs were certified for US emissions with KE-Jetronic and catalysts. When someone says “300 hp,” ask which market brochure they are holding.
Why emissions cut the peak
Catalysts, calibration, and related equipment trade peak power for legality and drivability under US rules. That does not make a healthy US 560 slow in the classic sense — it makes brochure wars useless.
Torque and 0–60
Day to day you feel torque and gearing for merges. Period 0–60 tests vary; treat them as bands. A tired fuel system will feel slower than any brochure gap between markets.
Can you add power?
Euro exhaust/cam fantasies collide with emissions laws, KE complexity, and the point of a classic cruiser. The best “mods” on most cars are correct fuel pressures, ignition health, cooling, and compression. Stay legal where you live.

On an R107 this means verifying the condition on your year/engine before ordering parts. When in doubt, match the data card and engine number, then confirm with a specialist who works on 107s regularly.
